The structure and spectroscopy of compounds with 1,4,8,11-tetraazacyclotetradecane and manganese (III), nickel (II), and iron (II) : [thesis]

This thesis involves reactions of cyclam with Mn(III), Ni(II) and Fe(II). The chemistry of each metal with cyclam will be presented in sections discussing each metal. The initial intent of this thesis was to examine and compare the structures and electronic spectra of a series of trans monomeric first row transition metal cyclam compounds. Both Mn(III) and Ni(II) form such trans monomeric complexes with cyclam and their structural and electronic characteristics are, indeed, examined in this thesis. However, in the course of our study, we found that Fe(II) and cyclam in acetonitrile in the presence of oxygen form a di-macrocycle shown here: [See PDF
